The Click Adjustable option is available on our Custom Sizer dies as well (7/8”-14 format dies only)! Please note: The Click Adjustable Sizing Die will not work with the Dillon 550 or 650 press.

Included with the Click Adjustable Sizer Die is a Shoulder Bump Gauge.  This gauge attaches to standard calipers and allows measurement from the case shoulder to the base.  Using the Shoulder Bump Gauge with the Click Adjustable Sizer Die will make the proper sizer die setup easier than ever before.

Click Adjustable Die Instructions

Click Adjustable Sizer Die

As handloaders have become more aware of shoulder bump and proper adjustment of the sizer die in recent years, there has become a need for an easier way to adjust the sizer die properly.  Until now there have been few options other than trial and error to get the shoulder setback correct.  Anyone who has done this can attest that it’s a slow and imprecise job!

Whidden Gunworks has solved the problem with the new Click Adjustable Sizer Die. Patent No: 10,393,488.  This die and lock ring work together to give the user a clicking feel to the adjustment just like a high end rifle scope.  Each click moves the shoulder bump .001” so you can easily find the exact shoulder bump that you desire.
